predictive analytics are discoveries of micrological propensities that are not directly correlated with human understanding and affectivity and that do not by themselves cohere into clearly identifiable events (M. Hansen 2015, 111–12)
Whatever explanatory and causal value predictive analytics of large datasets have is, I suggest, ultimately rooted in this ontological transformation whereby probabilities are understood to be expressions of the actual propensity of things (M. Hansen 2015, 120)

The advent of recommender systems
In everyday life, we rely on recommendations from other people. … Recommender systems augment this natural social process. In a typical recommender system, people provide recommendations as inputs, which the system then aggregates and directs to appropriate recipients. In some cases the primary transformation is in the aggregation; in others the system’s value lies in its ability to make good matches between the recommenders and those seeking recommendations.(Resnick and Varian 1997, 56)

Multiplicity will be called ‘closed’ when grasped by the numerical one, and ‘open’ when grasped by the vital One. Every multiplicity is the joint effectuation of the closed and open, but its ‘veritable’ multiple-being lies on the side of the open. (Badiou 2004, 72)
A concept of the open is substantially established once we possess a multiple such that the we dwell within it by taking the intersection of two elements, or the union of many elements as we wish (even an infinity of elements). In the other words, the intersection of two opens is an open, and any union whatsoever of opens remains open. (Badiou 2004, 73)
Tesco surplus
Straight to the checkout?
This means, to put it slightly differently, that surrounding any delimited predictive system is a larger field of data – what I elsewhere call a “surplus of sensibility” – that, viewed speculatively, indexes the causal efficacy of the total situation within which this delimited system operates. (Effectively, the latter gains its reliability from closing off this larger surplus of sensibility, thereby transforming an always excessive propensity into a [provisionally] closed dataset.) Because it affords data that exceed whatever any given predictive system might include, the data of the world’s causal efficacy – the data constituting its real potentiality – always and in principle facilitates knowledge that cannot be restricted to any particular agenda (M. B. N. Hansen 2015, 126–7)
